What should be noted when replacing the battery of a Mercedes GLE400?

[Barbara]

For Mercedes-Benz series models, when replacing the battery, unlike other German cars that require matching, as long as the battery model and ampere-hour rating match, no matching is needed. It is important to note that when installing the battery, the positive and negative terminals must not be reversed. What should be noted when replacing the battery? 1. When replacing the battery, it is necessary to replace it with an AGM battery of the same specifications as the original. If a general battery is replaced, due to different specifications, the engine module may judge the supply voltage as too low, resulting in the inability to eliminate the fault indicator light. (1) If replacing with the power disconnected, first take the key out of the car and wait for 5 minutes to allow the vehicle to enter sleep mode before replacing. (2) If replacing without disconnecting the power, be careful not to let the positive terminal touch the car body during the replacement process, as this may cause other phenomena such as module fault indicators. 2. When connecting the battery terminals, connect the positive terminal first, then the negative terminal. After installation, anti-rust protective agent or acid-free grease can be sprayed on the battery terminals for protection. When the Mercedes ammeter pointer shows insufficient battery charge, it should be charged in time. The battery charge of the Mercedes E-Class can be reflected on the dashboard. Sometimes, if you find the charge is insufficient on the road and the engine stalls and cannot be started, as a temporary measure, you can seek help from other vehicles, using their vehicle's battery to start the vehicle by connecting the negative terminal to the negative terminal and the positive terminal to the positive terminal.
